Internally the blast furnace is considered to consist of five discrete zones, see Fig. 17.2, through which all furnace gases and/or liquids must pass.The location, shape and extent of each zone is influenced by the properties of the material layers (relative thickness, etc.) and by the properties of the materials themselves. These factors interact to determine the flow and distribution of

Reducing the environmental impact of blast furnaces

A serious environmental impact of Russian blast furnaces is the generation of copious dust on account of the low strength of the sinter and pellets employed. Their strength may be increased if red mud from alumina production is introduced in the initial batch. A problem here is that the red mud lowers the iron content in the blast-furnace batch. However, this effect may be compensated by
